poration ofl'Kansas Appiication-Gctbben, 1944; Scritti-Noz 5613040 7.Clai'ms.- (Cl. 251-132') This invention. relates to: valves; and more particularly-to valvesfhaving: at plurality.v of outlet. lports requiring; ai plurality .offcarriage and poppet assemblies in said ports for the ilowiof fluids. Heretofore in valves of this type.: and particularly' in valves requiring; a` cartridge as- Sembly,. it hasrequlred a great many moving parts which ,cal-lsedi` excess friction and wearing ont ofsuch parts.

`Itri-san'object of thepresent invention, therefore-.tomakeva simple, economicaly and efcient valve structurel having few vvork-ingvparts; to provide for positively opening and-` closing the' valve.; toprovide a carriage-and poppet assembly for; saidvalve-having areverse action to positively open and close said-valve; to provide a cam for actuatingl the cartridgeassembly which also acts as an index' for said valve for indicating when. thesvalvefis open or closed, and to vprovide means for positively retaining'the valve in openor closed position.

In accomplishing these and-other objects of the invention, I- have provided improved details of Structurae; the-preferred form of which isillus traitedin theiaccompanyingfdrawings wherein.:

The poppet 3l is provided with an upstanding peripheral flange 45 around its outer periphery providing an annular groove 46 in the top of said poppet member.

I also preferably provide a flat cylindrical ring 41 preferablyY made of steel or other suitable ma'- terial adapted "to fit in the port and rest on the circumferential ange 26 of the cage 25. I also provide a ring 48, preferably made of rubber or other resilient material, having an annular groove 49 around the outer circumference thereof adapted to receive the flat ring 41 which extends inwardly from the ange 26 ofthe cage providing a seat for the poppet 3l.

Internally screw-threaded flange ttings 50 are provided for the port openings 5 and 6 having their inner end resting on the rubber ring 48. I also preferably provided a gasket ring 5l preferably made of rubber or other resilient material adapted to rest on the rounded shoulders 52 of the body member for sealing the ttings in said ports.

When the parts of my device, above described, are assembled, -the rounded end-34 of the pin 33 of the poppet assembly engagesthe rim of the cam i8 as indicated at 53, Fig. 3, and the valve is then in closed position. When the rounded endV 34 of the pin 33 is engaged inthe detent I9 of the cam I8 the valve will be open as shown in Fig. 4.

Operation of a valveconstructed and assembled as described is as follows:

When it is desired to close the valve, shaft I4 may be turned through manipulation of the yoke l1 so that the end 34 of the pin 33 of the poppet assemblies cont-acts the outer periphery 54 of the cam I8. When it is desired to open the valve, the shaft is turned so that the end 34 of the pin 33 engages in the detent i9 of the cam and the springs 42 will exert pressure on the crossA pin 35 which in turn exerts downward pressure on the poppet 3| thus opening the valve.A It will thus be seen that only one outlet portmay be open at one time for the reason that only one pin` may enter the detent., Further turningof the shaft i4 will close the valveas above described by raising the V`pin out of thefdetent i9. When the valve is closed the flange 45 of the poppet 3l contacts the rubber ring 48 so that no fluid can pass therethrough. It is believed apparent, therefore, that the present invention provides a simple, compact and eiliclent valve adapted for kuse as described.
